FIELD OF INVENTION

This disclosure relates to display panel manufacturing technology, andmore particularly to a liquid crystal material and liquid crystaldisplay panel.

BACKGROUND OF INVENTION

With development of display technology, liquid crystal displays (LCDs)and other display panel devices have advantages, such as high imagequality, power saving, thin body, and widely used, for wide applicationsin mobile phones, televisions, personal digital assistants, digitalcameras, notebook computers, desktop computers, and other consumerelectronics products, and have become mainstream in display devices.

Most liquid crystal display devices on the current market are backlitliquid crystal displays, which comprise liquid crystal display panelsand backlight modules (BM). A working principle of the liquid crystaldisplay panel is to dispose liquid crystal molecules between twoparallel glass substrates. There are many vertical and horizontal smallwires between the two parallel glass substrates. The liquid crystalmolecules are controlled to change direction by energizing or notenergizing for refracting light of the backlight module to generate apicture.

Thin film material layers are disposed on a CF substrate and a TFTsubstrate of a liquid crystal display, respectively. Its main functionis to align the liquid crystal molecules in a certain direction. We callit an alignment film (usually polyimide (PI) material). The alignmentfilm mainly includes a frictional alignment PI material and aphoto-alignment PI material. However, each kind of alignment materialhas its own disadvantages. First of all, friction alignment can easilycause dust particles, static electricity residue, brush marks and otherproblems, thereby reducing process yield. Photo-alignment materials canavoid these problems. However, due to limited material properties, poorheat resistance and aging resistance, and an ability to anchor LCmolecules simultaneously is weak, and quality of a panel is affected.Secondly, PI material itself has high polarity and high waterabsorption, storage and transportation of the PI material are prone tospoilage resulting in uneven alignment, and the PI material isexpensive. A process of film formation of the PI material on TFT-LCD isalso more complicated, resulting in increased panel costs.

Therefore, there are some small-molecule additive materials that canreplace the PI materials. It mainly includes alkyl chain-containingsilanes, cage-type silsesquioxanes, alkyl chain-containing alcohols, andthe like. These small-molecule additive materials mainly rely on theirown polar groups to adsorb on a surface of a substrate, so that theliquid crystal molecules can be vertically oriented. A liquid crystalmaterial containing the additive material is called a self-alignedliquid crystal material.

Applying this material to TFT-LCD panels often has problems, such as LCDpanel topography surface difference. A main reason is that a surfacestructure of the TFT-LCD panel is a “*” slit pattern. An area where apixel electrode is located is divided into an area covered by an ITOpixel electrode and an area not covered by the ITO pixel electrode,while the area not covered by ITO pixel electrode is mainly apassivation layer. The passivation layer is generally comprises ainorganic material silicon nitride and an organic material insulatingfilm PFA (Polymer Film on Array). When a PI alignment layer is notapplied, and the additive material is adsorbed on the surface of thesubstrate for alignment, due to the weak interaction between theadditive material and the SiNx/PFA, a difference in an acting forcebetween an auxiliary alignment agent and the surface of the substrateleads to poor alignment. It is easy to cause drawbacks, such as darklines or bright lines, after a voltage is applied.

Thus, it is necessary to improve the additive material so as to improvea function of anchoring the substrate, and solve the problems ofalignment force difference, the drawbacks of the bright lines and thedark lines due to pixel electrode differences, thereby achieving uniformalignment.
